T0 all whom t mag] concern:

Be it known that l, GEORGE P. S1muous, a citizen of the U ited'f3tates, residing at Herkimer, in the county of Herkimer and State of New York, have invented certain new and useful I:nprovements in -Lubricators, of which the following is a specification.

This invention relates to 'luhricators, and particularly to lubricators for attachment to the brasses used in railway car journal boxes. The invention is an improvement on the structure described and clamed in the patent to Gr. P. and B. M. Simmons, No. 1,122,036, gra:ited)ecember 22, 1914.

In the structure described in that patent a wicl:, composed of metal and fiber strands, is used to conduct oil from the bottom ofthe journal box to the journal, at or near the edges oft1e brass. This wicl: issupported and confined by a bracket whichextends the entire length of the brass and on two sides. In the use of said device it has been found that the life of the W0l is limited by the packing andchoking of the wick where it contacts with the journal.

I have discovered that this packing and choking is due to a slight rocking of the hrass in reverse directions as the journal turns in one or the other direction, This pinches the wick between the journal and the bracket, and limite its oil absorbing quality 'to suchan'extent as'o iten to require wicks to be cli scarded before they are much worn.

l have found that this dilficulty can be overcome by so changing the form of the wick-supporting means as to leave the wick tree throughout substantially its entire length of contact with the journal, and yet so direct and suoportthe wick that it maintains contact with the journal. To accomplish this result I mak -use of specially formed brackets arranged in pairs, one at each end of the brass.

The preferred embodiment of the invention is shown in the accompanying drawing, in Which,

Fig. 1 is a transverse section on the line 11 of Fig. 2.

Fig. 2 is a longitudinal vertical section through the journal box at one side of the journal, showing the invention applied.

Fig. 3 is an enlarged fragmentary view showing one bracket attached to a brass.

Itenewecl October 7, 2.922. Serial No. 593,143.

4 is a section on the line l4: of

Fig. 5 is a perspective view of a bracket removed from the brass.

Fig. 6 is a perspective view of a spring lock washer suitable for retaining the attaching screws.

A journal box of usual form is shown at 11, and is provided with the usual lid 12, brass 18 and wedge 14. All these partsmay be of any usual construction, and hence may depart from the exact form shown in the drawin9.

Fastened to the sides of the brass, near the ends thereof, are four pressed metal clips indicated generally by the numeral 15, two 0 Which a re reversed with respect to the other twoso as to oppose each other at opposite ends of the brass. The two clips on a side of the hrass are therefore symmetrical with respect toa line.

Each clip 15 includes an attaching plate 16, formed with a hole 17 and a dowel pin 18, a wick-confiningbow 19, and an eye 20. The lower edge of the eye 20 is reinforced by folding over a part of the metal, as is shownat 21. This gives a rounded edge and avoids chafing of the wick this point.

The sides of thebrass 13 are drilled near its ends to receive the dowels 18, and are dril led and tapped to receive attaching screws 22, which are passed through the holes 16 and are locked by spring washers The clips are so mounted on the brass that the =bows I9 on one side of the brass projedttowa d each other.

The wiclr 24, which may be, and p1efer aloly is otthe type described and claimed in Patent 1,122,037, granted December l9 14, to -Simmons and Simmons, is threaded through the eyes 20 and under the bows 19 in the ma nner clearly gshown in the drawings,, so .htt"it has portions extending along the journal at each side of the brass, and pendent portions at each end of the brass. This ensu1es such support for the wick as will hold it in contact with the journal at each side of the brass and throughout the length of the brass, and yet leaves the wick free enough to yield if the brass shifts. The l wick-confining bows are lon9; enough to fix the direction of the wick, but are carefully so proportioned as to preclude pinching of th wick between the how and journal. The eyes 20 are bounded at their sides adjacent the ends of the brass by the reversely curved member of the clip, and this is so proportioned as to deflect the wick just enough to retain it against slipping, without causing it to be sharply bent or mashed where it passes through the clips.

The pendent ends of the wick may extend to and lie in oil in the bottom of the box, or if it is desired to ensure a feed of new oil, the ends of the wick adjacent the end of the journal may be placed in an auxiliary oil reservoir 26, such as is shown in the prior patents above mentioned. Whether the reservoir 26 is, or is not used, the functions of the wick and the clips are the same.

The efi'eot of the use of the wick is to feed the oil at the proper rate to the journal, and to keep the oil fluid regardless of atmospheric temperature. In performing these functions the fibre strands feed the oil, while the metal strands conduct heat from the journal through the body of the wiclr to the oil in the box. The metal strands also give a desirable stiflness to the wick as a whole, so that between the clips it is held in contact with the journal by its own inherent rigidity.

The dowel 18 may obviously be formed integral with the bracket as seen in Fig. 5, by pressing or drawing, and in practice this will doubtless be advantageousin that it simplifies and cheapens production( Any suitable absorbent wick or feeder may be employed. 7

Obviously, any known or usual means of attachment may be adopted for the clips,

including welding, or casting with the 'brasses, and the like, the invention residing primarily in the provision of independent brackets or clips at or near opposite ends of the brass, and the manner of attachment being variable at will within the known and usual modes of accomplishing the same.

The provision of separate clips permits the ready equipment of brasses already in use, with my lubricating device or attachment, but where new brasses are to be cast it will be found convenient, and probably economical, to form the same with integral ,members at the four corners having eyes through which the wick may be led, and by f which it will be directly supported and held in contact with the journal from eye to eye, asaboveindicated. As it is desired to claim specifically the integral construcagainst said .brass; a wick composed of fibrous and metallic strands; and clips mounted on the sides of said brass, near the ends thereof, and having eyes with adjacent bowed retaining portions serving to retain the wick in contact with the journal at points intermediate said clips, through the inherent rigidity of the wick.

2. The combination of a journal box; a brass mounted there1n; a ournal turning 'against said brass; an absorbentwick; and

clips detachably secured to the sides of said brass, near the ends thereof, and having eyes with adjacent b0wed retaining portions serving to retain the wick in contact with the journal at points intermediate said clips.

3. The combination of a journal box; a brass mounted therein; a journal. turning against said brass; a wick composed of fibrous and metallic strands; and wick retaining clips on the sides of said brass near the ends thereof, said clips having loops of sufficient length to retain the intermediate portion of said wick-in contact with said journal by the inherent rigidity of thefiwi ck,

and having wick deflecting portions serv1ng to deflect the projecting ends of the wick to frictionally retain the wick against movement in the direction of itslength.

4. The combination of a journal box; a brass mounted therein; clips rigidly and directly secured to the sides of said brass near the ends thereof and formed with Wickretaining loops; and a wick carried bysaid clips and by them held in contact withthe 7 journal from clip to clip. 7 5. The combination of a journal box; a brass mounted therein andprovided on its sides near the ends thereof with wick-retaining clips; and a wick composed of fibrous and metallic strands, carried by said clips, and by them held in contact with the journal from clip to clip. In testimony whereof I have signed my name to this specification, 7
